Lorraine and Maggie Baines/McFly/Tannen--Back to the Future I-III
Kelly Ann Murkowski--Jaws 3D
Beverly Switzer--Howard the Duck
Sylvia Vane--Tales from the Crypt
Lea Thompson has not done any genre work in twenty years and some of it outside of the Back to the future trilogy is an acquired taste, but she still ranks near the top of my favorites. I left the 80’s without crushing on Molly Ringwald, but not without crushing Thompson.
She still has it at fifty. (Yikes--fifty!)
Even talking ducks went for her back then.
